National team manager Vahid Halilhodzic branded Japan's 3-3 draw with Haiti on Tuesday "the worst match I have seen" and warned his players to shape up or be humiliated in next month's friendlies against Brazil and Belgium.

"I've been a manager for many years and I've never seen a match as bad as this," Halilhodzic told reporters after Shinii Kagawa had saved Japan from an embarrassing friendly defeat to the Caribbean minnows with a 92nd-minute equalizer at Nissan Stadium.

"People would think I was ridiculous if I started talking about the World Cup after a match like this. I have to apologize to the supporters. They came out and created a great atmosphere, the perfect conditions for us to play in. We couldn't live up to that and that's my responsibility."
